CPP 45111 Details

If you are installing an in-line fuel pump or an aftermarket fuel-injection setup but are using an original fuel tank not originally provisioned for a return line, this universal return line fitting kit is a simple and inexpensive way to add one to your existing setup without having to go through the hassle of pulling your old tank and installing an expensive, brand new tank. To install this fitting drill a hole in the fuel tank where you would like to position your return line, place the bung against the tank along with the supplied gasket, and use the supplied bolt with washer to effectively rivet the fitting in place. Once the bung is secure, remove the bolt and install the 1/4" NPT fitting and you're all set. This fitting can also be used for other applications such as adding a vent line or power steering return line, whatever you might need where a return line was not originally installed.

Used this in a '68 Camaro, original fuel tank, Holley in-tank electric fuel pump, with Atomic EFI. The previous owner didn't have a recirc line and while the pump is supposed to be PWM, it burned out more than once. Since using this bung and a pressure regulator, have had no problems.

The parts that are being produced these days are often cheap and you get what you pay for. This is not the case here. You can tell that this is machined well and is well thought out. It will allow you to easily add a return fitting to a fuel system that was designed without one
